ABSTRACT:
A catalyst system suitable for olefin polymerization comprising a catalyst component made up of chromium on a phosphated alumina or low phosphorus aluminum phosphate base and optionally an organometal cocatalyst. The resulting catalyst is particularly sensitive to the effects of hydrogen as a molecular weight control agent, thus allowing the production of polymers of having a melt flow varying over a wide spectrum utilizing the same catalyst.
